Xiaoyu Yao commented on HDFS-10906: ----------------------------------- Thanks [~hanishakoneru] for working on this to improve the unit test coverage. The patch looks good to me overall. I just have a few comments. *TestTrashWithEncryptionZones.java* 1. Unused imports import org.apache.hadoop.fs.FileStatus; import org.junit.rules.Timeout; import org.junit.runners.MethodSorters; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.junit.AfterClass; import org.junit.BeforeClass; import org.junit.FixMethodOrder; 2. We can remove the EncryptionFaultInjector if it is not used in the test. {code} @After 119 public void teardown() { 120 if (cluster != null) { 121 cluster.shutdown(); 122 cluster = null; 123 } 124 EncryptionFaultInjector.instance = new EncryptionFaultInjector(); 125 ... {code} 3. verifyDelete() We can use the Path constructor that takes two parameters to avoid concat the path with "/" {code} 203 final Path trashFile = new Path(shell.getCurrentTrashDir(path) + "/" + 204 path); {code} 4. testDeleteEZWithMultipleUsers() Some of the verification of positive cases can be simplified by verifyDelete(). Combining with the verifyDelete() in TestTrashWithSecureEncryptionZones, I think we can add it to test utilities such as DFSTestUtil for better reuse. NIT: extra empty lines around 156 *TestTrashWithSecureEncryptionZones.java* 5. Unused imports import org.slf4j.Logger; import org.slf4j.LoggerFactory; 6. NIT: many instances of local variable len can be a static member of the class {code} final int len = 8192; {code} 7. testTrashExpunge Can we add verification of case where expunge will delete checkpoint inside the encryption zone when the whole encryption zone has been deleted and moved to trash directory under /user/$USER/.Trash? > Add unit tests for Trash with HDFS encryption zones > --------------------------------------------------- > > Key: HDFS-10906 > URL: https://issues.apache.org/jira/browse/HDFS-10906 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: encryption > Affects Versions: 2.8.0 > Reporter: Xiaoyu Yao > Assignee: Hanisha Koneru > Attachments: HDFS-10906.000.patch, HDFS-10906.001.patch > > > The goal is to improve unit test coverage for HDFS trash with encryption zone > especially under Kerberos environment.
